Valvetrain questions?

Look at the valve springs and seal first... There are three types you might find: Stock springs that have a single would wire (Comp's generally will not be these). Second is a high performance general use spring, which has a single round wire plus a flat wire inner dampener (you can see the flat metal winding...) Third are higher performance dual springs which have the round outer wire spring, then the flat wire dampener, then a single smaller round wire inner spring. The second type can use either type of valve seals I mentioned. Umbrella type seals are factory and are large and black. They will fill up the spring. Positive seals are smaller and usually white or gold in color.
